Fenomena banjir perkotaan di Kelurahan Bumi Waras disebabkan oleh perubahan alih fungsi lahan yang semakin meningkat tanpa memperhatikan pembangunan sistem saluran drainase. Banjir drainase perkotaan adalah banjir yang terjadi hampir setiap tahun ketika kondisi drainase tidak berfungsi dengan baik akibat tumpukan sampah. Tujuan utama penelitian tugas akhir ini adalah untuk mengidentifikasi lokasi banjir drainase di daerah Teluk Lampung terutama di Kelurahan Bumi Waras. Data yang digunakan yaitu data primer dan data sekunder. Data primer berupa hasil tracking aliran air di lapangan dan data sekunder berupa data Digital Elevation Model nasional (DEMNAS) serta shapefile sungai Kota Bandar Lampung. Identifikasi lokasi banjir drainase menggunakan metode analisis hidrologi. Berdasarkan hasil analisis hidrologi menggunakan data DEMNAS didapatkan bahwa, aliran air Kelurahan Bumi Waras berasal dari hulu ke hilir. Terdapat dua lokasi aliran air yang terputus berdasarkan hasil tracking aliran yaitu di sekitar Lampung City Mall dan Perumahan Nila Rahayu, Lingkungan III, Kelurahan Bumi Waras. Banjir drainase di Kelurahan Bumi Waras disebabkan oleh air kiriman dari pusat Kota Bandar Lampung yang mengalir melalui drainase existing dan sekitar jalan. Namun, drainase existing tidak mampu menampung debit air sehingga air meluap ke permukaan. Penelitian selanjutnya diharapkan dapat menghitung sedimentasi sungai di Kelurahan Bumi Waras untuk identifikasi kapasitas debit air.

Urban drainage flooding is a flood that occurs almost every year when drainage conditions do not function properly due to piles of garbage. The main purpose of this final project research is to identify the location of drainage floods in the Teluk Lampung area, especially in Bumi Waras Village. The data used are primary data and secondary data. Primary data in the form of tracking drainage line points in the field and secondary data in the form of national Digital Elevation Model (DEMNAS) data and river shapefiles in Bandar Lampung City. Identify the location of drainage floods using hydrological analysis methods. Based on the results of hydrological analysis using DEMNAS data, it was found that the water flow of Bumi Waras Village came from upstream to downstream. Based on the results of flow tracking, there are two locations where the water flow has been cut off, namely around Lampung City Mall and Nila Rahayu Housing Complex, Ward III, Bumi Waras Village. Drainage flooding in Bumi Waras Village is caused by water sent from the center of Bandar Lampung City which flows through existing drainage and around roads. However, existing drainage is not able to accommodate water discharge so that water overflows to the surface. The next study is expected to calculate river sedimentation in Bumi Waras Village to identify water discharge capacity.
